Adding PageSize item to RadGrid PageSizeCombo

[Chris]

Hi,

I have added the code below to the ItemDataBound event of a grid for which I want users to be able to select 100 as the Page Size. This works, but now I find that when I select this new item the grid does not do a postback and refresh. Could you please advise?

Thanks
Chris

            if (e.Item is GridPagerItem)
            {
                RadComboBox PageSizeCombo = (RadComboBox)e.Item.FindControl("PageSizeComboBox");
                RadComboBoxItem extraItem = new RadComboBoxItem("100", "100");

                if (!PageSizeCombo.Items.Contains(extraItem))
                {
                    PageSizeCombo.Items.Add(extraItem);
                }
            }

Hi Chris,

If you want to customize the page size combobox, see the Shinu's post in this forum thread.

Hi,

Thanks for the response, but isn't that essentially what I have done? The key line being:

RadComboBoxItem extraItem = new RadComboBoxItem("100", "100");

Thanks
Chris

Hello Chris,

To achieve your goal you should add extra item as below:
C#:

RadComboBoxItem extraItem = new RadComboBoxItem("100", "100");
extraItem.Attributes.Add("ownerTableViewId", RadGrid1.MasterTableView.ClientID);

Hi,

I have the same requirement as mentioned in the forum entry. The solution you suggested works fine except for one unwanted side effect. When I selected 100 as pagesize every thing works fine but the value shown in RadComboBox as selected is shown as 10 ( the first item of ComboBox). But the pagesize is 100 and when I click on forward or back pages the pagesize is still 100 but value shown in ComboBox is 10.

Hello Bhupinder,

You can try the following code snippet in ItemCreated event to show the value in PageSizeComboBox same as that of selected page size.
C#:

protected void RadGrid1_ItemCreated(object sender, GridItemEventArgs e)
{
  if (e.Item is GridPagerItem)
  {
    GridPagerItem pagerItem = (GridPagerItem)e.Item;
    RadComboBox PageSizeCombo = (RadComboBox)pagerItem.FindControl("PageSizeComboBox");
    RadComboBoxItem item1 = new RadComboBoxItem();
    item1 = new RadComboBoxItem("100", "100");
    item1.Attributes.Add("ownerTableViewId", e.Item.OwnerTableView.ClientID);
    PageSizeCombo.Items.Add(item1);
    PageSizeCombo.Items.FindItemByValue(RadGrid1.PageSize.ToString()).Selected = true;
   }
}

Thanks,
Princy.
